13 Claims.

This invention relates to a device adapted for use in the manufacture ofshoes, and more particularly for the application of the so-calledsocklining on and around the edge of an insole.

n It is also probably useful for other purposes as will be apparent fromthe description appearing hereinafter.

The sock-lining of a shoe is usually a thin layer of sheet material,such as textile fabric, leather,

l simulated leather or the like, which in the shoe is in direct contactwith the foot or stocking worn by the wearer. In the construction of theshoe, the sock-lining is adhesively attached to the upper face of aninsole and the marginal edge of 15 the sock-lining is folded about theedge of the insole and adhesively attached to the under face of theinsole. The apparatus to which the present invention relates is one inwhich is performed the steps of folding the marginal edge of the sockglining around the edge of the insole and adhesively securing theinfolded edge of the socklining to the under face of the insole. Theobject of the present invention is to provide a mechanism for speedilyand effectively performing the steps just mentioned in a manner notheretofore contemplated whereby the shoe construction is not onlyimproved, but the manufacturing cost considerably reduced.

In the accompanying drawing, wherein several "0 embodiments of theinvention are shown, Fig. 1

is a face View of an insole and attached socklining, such as is operatedupon by the device constituting the invention; Fig. 2 is a sideelevation of the device with parts of the same in lon- 35 gitudinalsection, the section being taken on the line 2-2 of Fig. 3, looking inthe direction of the arrows; Fig. 3 is a plan view of the device withthe plunger means omitted, and parts broken away and other parts insection, to disclose con- 13;) struction; Fig. 4 is a fragmentarysectional view showing the device in its compressed position in the actof folding down the marginal edge portion of the sock-lining over theinsole; Fig. 5 is a sectional view on the line 5-5 of Fig. 3, looking inthe direction of the arrows; Fig. 6 is a sectional view of a modifiedstructure; Fig. 7 is a similar sectional View showing the device of Fig.6 in its compressed position in the act of pressing down the infoldedmarginal edge portion of the 50 sock-lining over the insole; and Fig. 8is a perspective view of one of the pressing elements shown in Fig. '7.

The character of the article upon which the improved apparatus isadapted to operate is indi- 55 cated in Fig. 1, where it will be seenthat the same consists of what is known in the shoe manufacture as aninsole I, the same being usually composed of cardboard or the like, andadapted to have one of its faces covered by a so-called sock-lining 2.The sock-lining 2 is, in the finished shoe, that layer of materiallocated within the shoe and in direct contact with the foot or stockingof the wearer.

In the construction of the shoe, the socklining is adapted to have itsmarginal edge por- 19 tion 3 shown projecting beyond the edge of theinsole, folded around the edge of the insole l and adhesively secured tothe bottom face thereof, indicated at 4. The present inventiontherefore, relates to an apparatus which folds the marginal edge portion3 of the sock-lining over the edge of the sole I and adhesively attachesthe folded over marginal edge 3 to the bottom face 4 of the sole. Thestructure of the invention simultaneously folds down and adhesivelyattaches the 20 entire marginal edge portion of the sock-lining to theface 4 of the sole.

In Figs. 2 to 5 of the drawing inclusive, a plate or similar element isshown at 5, the same being provided with an opening or aperture 6 of ashape 3. to permit the passage through it of the sole l. The opening 6,upon the passage of the sole I through it, causes the marginal edge 3 ofthe sock-lining to be folded to an upstanding position, as clearly shownin Fig. 5. Any suitable m) means may be employed for forcing the sole land attached sock-lining down through the cpening 6 to bring it to restupon a pivoted footshaped element or supporting base member 7 forming apart of a plate or similar member 8, located below, and spaced from, theupper apertured plate member 5. Extending between and connecting plates5 and 8 is a wall provided by a plurality of closely positionedarticulated members 9, the construction of which is more clearly shownin Fig. 5. These members consist of a plurality of links H! hingedtogether at ii and respectively hinged to the plates 5 and 8 at l2.These articulated members 9 are placed in close relationship so thatthey co-operate in the formation of a substantially continuous wall,shaped to conform to the aperture 6, so that when the sole 1 andattached sock-lining 2 is forced down through the aperture 6, theupstanding marginal edge portion 3 of the sock-lining will be main- .3tained in such upstanding position by being enclosed by said wall untilthe sole and attached sock-lining comes to rest upon the pivoted supportI. The plates 5 and 8 are normally held in spaced-apart relationship bymeans of springs I3 or other resilient elements which tend to also holdthe articulated links 9 in their vertically disposed position, clearlyshown in Figs. 2 and 5. When the sole and sock-lining comes to rest uponthe pivoted support I, plate is then forced downwardly toward plate 8causing the articulated members to fold or collapse inwardly on theirpivots H and 12 to thereby press downwardly against the then upstandingmarginal edge portion 3 of the sock-lining and fold it down fiatwiselyagainst the bottom face 4 of the insole. Since the entire sole issurrounded by the wall, composed of the articulated members 9. it willbe apparent that when said wall collapses inwardly as above explained,it will fold down simultaneously the entire marginal edge portion 3 ofthe sock-lining to cause it to overlie the face 4 of the sole and beadhesively secured thereto. It is of course, understood that themarginal edge portion 3 of the sock-lining is coated with an adhesive topermit of such adhesive attachment.

The means for thrusting the sole and attached sock-lining through theopening 6 in the plate 5 and also for causing the plate 5 to be, movedtoward the plate 8 to bring about the inward folding or collapse of thearticulated members 9 is clearly shown in Fig. 2. It will be there seenthat such means includes a plate I4 which may be shaped similarly to theopening 6 but of a smaller size, said plate being mounted on the ends ofstuds I5 which extend through an upper plate IS, the studs beingsurrounded by coil springs II holding the respective plates I4 and I5apart as shown in Fig. 2. Studs I5 are provided with heads I8 to limitmovement of plate I4 away from plate I 6. Plate I6 is attached to avertical shaft I9 which forms a part of any suitable plunger-operatingmechanism and is vertically reciprocable either by manual operation orby a suitable mechanical means.

In the operation of the device, sole I and attached socklining 3 areplaced as a unit over the opening 6 in plate 5 with the upper face ofthe sock-lining facing downwardly as shown in Fig. 2 and its marginaledge portion I3 preventing it and the attached sole from fallingdownward through the opening 6. The plunger upon its descent brings itslower plate I4 into contact with the sole I and forces it downwardlythrough the openings 6, finally bringing it to rest upon the pivotedsupporting member I. The effect of this downward movement of the soleand attached sock-lining is to cause the marginal edge portion 3 of thesock-lining to be folded upwardly to an upstanding position by itsengagement with the edge of the aperture 6 and with the vertical wallformed of the articulated members 9. Thus, when the sole and sock-liningreaches a position of rest on the upper face of the supporting member I,it is in the position shown in Fig. 5. When the plate I4 reaches aposition of rest upon the supporting member "I, the plate I6 continuesits further downward movement against the pressure of the springs I1 andsaid plate I6 being larger than the opening 6 in plate 5, it strikes theupper surface of the plate 5 and moves the same downwardly against thepressure of the springs I3. As plate 5 is moved downwardly toward theplate 8, the Wall composed of the articulated members 9 is collapsed orbuckled inwardly as clearly shown in Fig. 4, so that said wall forcesthe upstanding marginal edge portion 3 of the sock-lining downwardly andmwardly over the bottom face 4 of the sole, causing said folded downportion of the sock-lining to be adhesively secured to the face 4 of theinsole. When this has been done, the plunger rises to its elevatedposition shown in Fig. 3 to be positioned in readiness for the insertionof the next sole and attached sock-lining.

The supporting member I conforms in shape to the aperture 6 and itconsists of a plate pivoted at at its opposite ends and provided with aweight 2I at one side of a longitudinal line connecting the pivots, saidweight tending to normally maintain the supporting member 'I in aninclined position as indicated in dotted lines in Fig. 5. The descent ofthe plunger thrusting a sole and sock-lining down with it will tend tocause the pivoted supporting plate 1 to swing upwardly to the positionshown in full lines in Figs. 2 and 5, in which position it will be heldas long as the pressure of the plate I4 holds a sole and attachedsock-lining on it. As soon as the plunger rises at the completion of theoperation of folding down the sock-lining, the pivoted support I willassume its tilted or inclined position under the influence of the weight2|, and permit the completed sock-lining and sole to slide downwardlyfrom its upper surface by gravity to a suitably placed receptacle. Thepivoted support I is provided with one or more suitable stops 22 tolimit its upward pivotal motion under pressure of the plate I4.

In the embodiment of the invention shown in Figs. 6 to 8 inclusive, thecollapsible wall extending between and connecting the plates 5 and 8 iscomposed of a plurality of annular elastic elements such as indicated at23. These elements may be made of rubber or suitable elastic mate- 5rial and be placed adjacent one another in a manner similar to thearticulated members 9. When the plate 5 is moved toward the base plate 8in the manner heretofore described, the tubular elastic members 23 willbe collapsed as shown in Fig. 7, causing the portion of the same whichfaces inwardly to overlie and press downwardly the marginal edge portion3 of the sock-lining over the sole. To prevent lateral shifting of theupper plate with regard to the lower plate, guide pins 24 are provided,said pins surrounding the compression springs I 3.

From the foregoing, it will be obvious that with the structuresdisclosed, insoles and attached sock-linings may be speedily fed to aposition above the opening 6 and upon the descent of the plunger, themarginal edge portion 3 of each sock-lining may be folded over and downupon the sole and adhesively attached thereto. The entire folding downof the marginal edge of the sock-lining occurs simultaneously so thatthe work is very rapid, efficient and uniform. If desired, devices ofthis construction may be arranged in a gang, so that a number of solesmay be fed and operated upon simultaneously. These and othermodifications may be made in the structure without departing from thescope of the annexed claims.
